5. In an experiment to monitor the ascent of sap, the following treatments were carried out to a twig dipped in water. In which case wilting will be observed ?
(A) Bark removed             (B) Pitha removed .
(C) Twig cut into half        (D) Glucose added to water. 

Dear student
Please find below the solution to the asked query

The correct option is D.

The addition of glucose to water makes it hypertonic solution. This will result in the loss of water (xylem sap) from the xylem of roots which in turn will result in wilting of the leaves. 

Hope this information will clear your doubts about the topic.
